Electromyographic Analysis of Masticatory Muscles in Cleft Lip and Palate Children with Pain-Related Temporomandibular Disorders.

ABSTRACT: Aim:The aim of this study was to assess the electrical activity of temporalis and masseter muscles in children with cleft lip and palate (CLP) and pain-related temporomandibular disorders (TMD-P). Methods:The sample consisted of 31 CLP patients with a TMD-P (mean age 9.5?±?1.8 years) and 32 CLP subjects with no TMD (mean age 9.2?±?1.7 years). The children were assessed for the presence of temporomandibular disorders (TMD) using Axis I of the Research Diagnostic Criteria for TMD (RDC/TMD). Electromyographical (EMG) recordings were performed using a DAB-Bluetooth Instrument (Zebris Medical GmbH, Germany) in the mandibular rest position and during maximum voluntary contraction (MVC). Results:The rest activity of the temporalis and masseter muscles was significantly higher in TMD-P group compared with non-TMD children. A significant decrease in temporalis muscle activity during MVC was observed in TMD-P patients. There was a significant increase in the Asymmetry Index for temporalis and masseter muscle rest activity in the TMD-P group. Conclusion:Cleft children diagnosed with TMD-P have altered masticatory muscle activity, and this can affect their muscle function.

Project description:ObjectiveThis study aimed to identify clinical bottle-feeding techniques practiced by nurses for children with cleft lip and palate experiencing feeding difficulties.MethodsA qualitative descriptive design was used. Five anonymous questionnaires were distributed to each hospital, and 1,109 hospitals with obstetrics, neonatology, or pediatric dentistry wards in Japan were enrolled in the survey between December 2021 and January 2022. Participants were nurses working for over 5 years providing nursing care for children with cleft lip and palate. The questionnaire comprised open-ended questions about the feeding techniques across four dimensions: preparation before bottle-feeding, nipple insertion methods, sucking assistance, and criteria for stopping bottle-feeding. The qualitative data obtained were categorized according to meaning similarity and analyzed.ResultsA total of 410 valid responses were obtained. The findings regarding the feeding techniques in each dimension were as follows: seven categories (e.g., improving child's mouth movement, keeping child's breath calm), 27 sub-categories in preparation before bottle-feeding; four categories (e.g., closing the cleft using the nipple to create negative pressure in oral cavity, inserting the nipple to not touch the cleft), 11 sub-categories in nipple insertion methods; five categories (e.g., facilitating awakening, creating negative pressure in oral cavity), 13 sub-categories in sucking assistance; and four categories (e.g., reduced awakening level, worsening vital signs), 16 sub-categories in criteria for stopping bottle-feeding. Most participants responded that they would like to learn bottle-feeding techniques for children with cleft lip and palate who have feeding difficulties.ConclusionMany bottle-feeding techniques were identified to address disease-characterized conditions. However, the techniques were found to be conflicting: some inserted the nipple to close the cleft to create negative pressure in the child's oral cavity, while others inserted it without touching the cleft to prevent ulceration on the nasal septum. Although these techniques were used by nurses, the effectiveness of the methods has not been assessed. Future intervention studies are needed to determine each technique's benefit or potential harm.
